BTW your posts with your card purchases for rentals are really helpful! It is really hard to tell which card is a better investment for rental as rental utility and game utility doesn't really coincide...
Thanks for saying that. End of season is a fun time but i try to pick up the cards with long term value so the rarer the better and that i can afford. My favorite is mischievous mermaid which i buy up as many copies as i can. It has a high return and a card that every new player wants, strong and limited supply. A supply that gets smaller every week.
